【摘要】 通过建立主动悬架与电动助力转向集成控制模型,应用预测控制理论,进行了预测控制器的设计,并在Matlab/Simulink环境中进行仿真模拟。仿真结果表明:具有预测控制策略的主动悬架与电动助力转向集成系统不仅能明显改善车辆行驶平顺性,提高转向轻便性,并且对由路面输入引起的振动能够进行有效抑制,使车辆的操纵稳定性和乘坐舒适性均有不同程度的提高。更多还原

【Abstract】 An integrated model of active suspension system (ASS) and electrical power steering system (EPS) were established based on the predictive control theory that was used to design a MPC (model predictive control) controller. Computer simulations were carried out under the Matlab/Simulink environment. The simulation results showed that the integrated system of ASS and EPS with a MPC controller could not only apparently improve ride performance and vehicle handiness, but also effectively reduce the vibrations caused by road inputs.更多还原
